Unfortunately that code is rather critical as it is attempting to move
files into position atomically and not use lockfiles or hold locks.
Failing silently is bad, we should probably add a check the file exists
afterwards and error if it doens't.
That wouldn't solve your issue with that filesystem would make people
aware of it.
